SEGTIONAL EJECTOR FOR SLUG'r-CASTING MACHINES.

Specification of Letters Patent.

Patented May 2, 1916.

Application filed March 9, 1914. Serial No. 823,565.

To all whom it may concern:

Be it known that I, JOHN L. EBAUGH, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Sectional Ejector-s for Slug-Casting Machines, of which the following is a description.

My invention relates to that portion of a linotype or line casting machine or kindred machines, by which the cast slug is forced out of the mold.

The object of my invention is to provide a simple, convenient and reliable device of the kind described in which the operative width of the ejector blade may be changed at will to suit the length of the line being cast.

To this end my invention consists in the novel construction, arrangement and combination of parts shown and described and more particularly pointed out in the claims.

In the accompanying drawings wherein like or similar reference characters indicate like or corresponding parts: Figure 1 is a section of the mold and associated parts taken substantially parallel to and at the back of the ejector slide with parts removed and broken away to more clearly show the construction. Fig. 2 is a similar section taken at the front side of the ejector slide handle and indicator for changing the number of ejector blades employed. Fig. 5 is a section taken substantially on line 55 of Fig. 4.

In the drawings for the purpose of illustration, I have shown my improved ejector as applied to a Mergenthaler linotype machine, in which 1 is the mold slide, 2 the mold, 3 the ejector slide. connected to the operating mechanism by the rod 4, all of substantially the usual or any desired form or construction, and operated and controlled in the usual or any suitable manner.

My improved ejector consists of a series of blades or fingers 5, 6, 7, 8, 9, 10 and 11, or any desired number of similar blades or fingers, each of suitable thickness and width to properly cooperate with the mold in ejecting slugs therefrom. The several blades are arranged to lie edge to edge, one above the other, in the ejector slide and jointly to form a blade corresponding in width to the maximum capacity of the mold. Each blade, however, is adapted to cooperate with any blade or blades below it in the e ector slide to form a blade for a mold of a width correspondingly less than the maximum, the remaining blades merely resting loosely in the ejector slide during the operative movement of the ejector but comlng into alinement at each return movement, or retraction, of the slide so that the operative width of the ejector blade may be readily adjusted each time the ejector slide has completed its return movement. Any sultable means may be provided for this purpose. As shown, the blade 5 at the lower edge of the ejector slide is rigidly secured to the slide by means of a slot 12 at 1ts rear end, adapted to engage a pin 14: upon the slide. An opening is also formed in the blade to engage the pin 15 in the slide to secure the blade to the slide and to accurately position the blade longitudinally. The remaining blades lie loosely, edge to edge, between the mold slide and ejector slide at the rear end, and between the mold slide and ejector blade guide, (not shown) at the front end, to maintain the position of the blades vertically. The lower edge of the blade 5 and the upper edge of the blade 11 are guided by the mold slide to further maintain the blades in position. As shown a shoulder 16 is formed upon the upper edge of the blade 5 intermediate its ends, and the forward end of the blade, or portion adjacent the mold, is slightly wider than the part at the rear of the shoulder. The remainder of the blades are each slightly off-set. The forward portion of each blade is slightly elevated or above the rear portion, a shoulder being provided at each edge of each blade, except the blade 11 which of course requires no shoulder on its upper edge. Each shoulder is formed and positioned to cooperate with the shoulder upon the next adjacent blade to prevent anyinto line and moving them all back from the mold as usual where a single blade is employed.

Any suitable means may be provided to bring the blades into perfect alinement at the completion of each return movement of the ejector slide. In the form shown, a pawl 30 is pivotally mounted upon the mold slide with its upper end bent over and projecting through a suitable slot 31 in the mold slide into position to engage the rear end of the blade 11, when the ejector slide is retracted, and force the several shoulders into firm contact and insure the accurate alinement of the blades. As shown a spring 32 is attached to the upper end of the pawl 30 and extends to a suitable pin 33 upon the mold slide to resiliently maintain the pawl. in position. In the preferred construction also the several shoulders upon the blades are under-cut so that the engagement of the shoulders of adjacent blades will tend to draw the blades together to minimize friction of the cooperative parts. As shown, the shoulders on opposite sides of each blade are spaced from each other longitudinally of the blade to avoid reducing the cross section, thus securing the greatest possible strength for the blade.

Any suitable means may be provided to rigidly connect any desired number of the ejector blades tothe ejector slide in position to cooperate with the blade 5 during the operative, or forward movement of the ejector slide. As shown, a suitable transverse recess 3 is formed in the ejector slide 3 extending transversely thereof and a support 34 is positioned in said recess with its lower end projecting downward through a slot 34 in the lower portion of the mold slide. The support 34 is positioned in said slot and rigidly secured to: the ejector slide 3 by suitable dowel pins 35 or other convenient means and a pair of bearings 35, one at each edge of the support, are mounted at its lower end in position to receive the operating rod 36. A pinion 37 is mounted upon the operating rod 36 and positioned between the bearings 35. A key-way 38 is formed in the rod 36 and a key or other suitable means is rigidly secured to the pinion and extends into the key-way to prevent rotation of the pinion upon the rod without interfering with its longitudinal movement. A guide 39 is also attached to the lower end of the support 34 adapted to hold the actuating slide 40 in position upon the support and permit its free vertical movement. The recess 3 is preferably slightly deeper than the thickness of the support 34 and the upper end of the actuating slide 40 extends into the recess 3 and is accurately guided by the walls thereof. The portion of the actuating slide 40 projecting out of the recess is positioned directly in the path of the rear ends of the blades and corresponds accurately to the thickness of the blades, thus cooperating with the ejector slide to look any desired number of blades in position thereon so that an operative movement of the slide will positively move the blades so engaged to force a slug of any desired length out of the mold. The slide 40 is provided with a rack on one side adapted to cooperate with the pinion 37 so that by rotating the rod 36 the vertical position of the actuating slide may be adjusted as desired. The rod 36 extends forward to the front of the machine through a suitable support to a point convenient to the operator, and is provided at its outer end with suitable means for rotating the same. As shown, a pinion 41 is rigidly secured to the end of the rod 36 and a gear 42, provided with a knob or handle 43 on its front side, ismounted upon a suitable stud adjacent the rod 36, so that by rotating the knob 43 the rod 36 will be correspondingly rotated.

In the preferred construction a rigid pointer 44 is provided at the face of the gear 42 and a suitable scale is marked upon the face of the gear to accurately indicate the position of the actuating slide. In the preferred form also suitable means are provided to rigidly lock the gear in position. For this purpose a chamber 45 is provided in the bore of the knob and a spring 46 is positioned in the chamber adapted to engage the head of the stud and resiliently press the gear toward its support. A suitable pin 47 is provided in the face of the gear support and a series of openings 48 are provided in the gear, each adapted to engage the pin and thereby lock the actuating slide in position to engage the rear end of the blades it is desired to move forward with the ejector slide. In the preferred form also a blade support 50 is attached to the upper end of the actuating slide 40 directly 1n the plane of the blades and so positioned that when the actuating slide is raised to engage any of the blades the support 50 willbe in position below the next blade above the uppermost blade engaged by the slide 40 to support the rear end of the inoperative blades in position during the operative movement of the ejector slide.

Having thus described my improvement it is obvious that various immaterial modifications may be made in my device without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form or construction shown.
